Specification of Letters Patent.

Patented Mar. 10, 1914.

To all fr0/20m it may concern.'

l'e it known that I, THOMAS F. Moanissm', a citizen of the UnitedStates, and a resident of Nest Orange, in the county of Essex and Stateot New Jersey, have invented certain new and useful Improvements inDrilling and Niching Machines, ot' which the following is aspecitication.

The present invention relates generally to drilling and niehingmachines, especially tfor buttons made of ivory nuts, and has for itsmain object an eflieient automatic machine that will properly drill andniche bnttons.

One Yt'eatnre oit the invention resides in means tor bringing a workholder and niching memberl toward and away from each other. combinedwith means Jfor imparting a combined oscillating and reciprocatiiigmotion to the niching member. This may be accomplished in many ways, butpreterably the niching member ismonnted on a slidably adjiiistablepivot, the said niching member oscillatingaround and Vibrating withrespect to said pivot, and the said pivot reciprocating. 1n ett'ect themotion imparted to the niching member is a combined oscillating andlongitudinally vibrating motion which imparted to the niching 1nember aplurality oit times in rapid succession to each cycle of the machine.

The niche in a button is the slot which is formed in the face oi thebutton and which connects the holes drilled in the button. rlhe objectof this niche is to pro vide a thread groove below the t'ace of thebutton. To avoid wearing the thread, the niche must present no sharpedges to the thread. f lit is itor this reason that the niching tool isgiven the double oscillating and vibrating motion, the oscillatingmotion cntting the groove between the butto-ns and the 1vibrating motionrounding oil the corners where the niche joins the holes.

Other features oit construction, arrangement ot parts and combination otelements will appear as the speeilication proceeds.

n the accompanying drawings, the invention is embodied in a concrete andpreferred t'orm, but changes of construction may oit coarse be madewithout departing from the legitimate and intended scope ot theinvention as set forth in the claims hereof.

2S is the main reciprocating carriage on which the foregoing members aremounted7 and carrying also a reciprocating clamp slide 29 having theclamp 30.

The drilling tools are denoted by 31 and the niching tools by 32. Theselatter are mounted on the supporting member 34 of the niching tool slide33 which moves in the guides rThe slide 33 is operated from the mainreciprocating carriage by means of the connection 36 secured to saidcarriage as shown in `Fig. 13 and provided at the end adjacent to theslide 33 with a square collar 37 fitting loosely on the block 38 whichis supported on the eccentric 39. r1`his eccentric has a flange 40resting on the supporting member 34. Passing through the eccentric 39 isa bolt 41 secured to the slide 33. The supporting member 34 is providedwith an aperture 42 so as to allow the said supporting member tooscillate and vibrate in a manner hereinafter to be described. Theeccentric 39 is provided with an arm 43 secured to the lever 44 by meansof the set screw 45 adjustable in the slot 46. rlihe lever 44 is pivotedat 47 to a stationary part of the frame.

The main reciprocating carriage 28 slides in the guides 48 and receivesits motion from the worm gear 49, by means of the crank pin 50, cam 51,pivoted at 52 to the framework? and connecting rod 53 pivoted at itsrespective ends 54 and 55 to the cam 51 and slidev 28. The worm gear 49receives its motion from the worm on the shaft 57, which latter receivesits motion in any suitable manner, as by means of the pulley 58.

As the main reciprocating carriage advances toward the drilling` tools31, the slide 33 will follow, owing to the connection 36. This movement,however, causes the lever 44 to turn the eccentric 89 thereby causingthe slide 33 to lag behind advancing` movement of the main reciprocatingcarriage. When the main reciprocating carriage returns, the slide 33will lag in the other direction.

The supportino' member 34 is attached to the slide 33 by means of a.slidably adjustable pivot constructed as follows: The supporting member34 is provided with a slot 76 and the slide 33 has a slot 77 somewhatnarrower than the slot 76. Seated in the slot 76 is a slidablyadjustable block 78 in contact with the sides of the slot but smallenough to leave the end spaces 79 unoccupied. A. pivot bolt 81 passesthrough the block 78 and is adjustable therewith.

Mounted on the supporting member 34 is the eccentric 59 through whichpasses the bolt 60 on which is the pinion 61, said bolt 60 having abearing in the socket 33a of the slide 33. rEhe bolt 60 is adjustable inthe eccentric 59 by means of the two set screws 62 whereby theeccentricity of the pinion can be varied. Meshing with the pinion orgear 61 is a sector 63 mounted to oscillate on the stud 64. The gearsector 63 is operated from the countershaft 65 which receives its motionfrom the shaft 57 by means of the pinion 66 and gear 67. The shaft 65carries a disk 68 having a slot 69 to which is attached a stud 70 of theconnection 7l which latter is provided with universal joint 72 and 73.The connection 71 is secured to the gear sector 63 by means of theeccentric stud 74 which is adjustable by means of the handle 75. Thestroke of the sector is adjusted by moving the stud 70 in the slot 69.

The action of the sector 63 causes the pinion 61 to oscillate, and, withit, the eccentric 59. rlhe oscillation of the eccentric causes thesupporting member 34 to oscillate around the pivot 81, and also tovibrate longitudinally of the block 7 8, in quick succession a pluralityof times to each stroke of the slide 33.

rlhe work holder 26 has a rotatable member 26a mounted on the mainreciprocating carriage 28 and interposed between the drilling andniching tools, and rotates in a plane at right angles to the movement ofthe said carriage. This rotatable member is provided with pockets 83 andis partially surrounded by a stationary peripheral raceway 84 having acam 85 which is adjustable by means of the screw 86 and is adapted toengage the buttons 87 to move the same radially inward to center themwith respect to the tools. vided with projections 88 to prevent the edgeof the buttons from moving sidewise, and carries pins 89 by means ofwhich it is rotated. rEllis rotating motion is imparted intermittentlyby means of the pawl 90 pivoted at 91 to the transverse slide 92. rlhetransverse slide obtains its motion from the. main reciprocatingcarriage 28 by means of the slotted link 93 engaging with the roll 94 onthe transverse slide and pivoted at 95 to a stationary part of themachine.

96 is an arm carried by the main reciprocating carriage and connected bymeans of the link 97 to the slotted link 93. The motion of thereciprocating carriage 28 thus moves the transverse slide 92.

rihe raceway 84 is provided with a chute 98 located adjacent to theintermediate button delivery member 27. rllhe member 27 is pivoted at 99on the bracket 100 and is provided with a. supporting shoulder 101.Mounted on the transverse slide 92 is an upright 102 which is connectedto the member 27 by the following means: 103 is an arm. on the pivot 99connected to a link 104. This link is connected to a pivoted lever 105on the upright 102 by means of the spring 106 and by means of a pivot107.

108 is a stop on link 104.

1li/Then the transverse slide 92 moves, it will7 through the connectionsjust described,

rlhe member 26 is further pro-V cause the member' 27 to oscillate, thestop 108 normally preventing the spring 106 from exerting its force tobring the outer ends of the link 101 and lever 105 together, but if abutton is jammed so as to prevent the member 27 from completing itsoscillating motion, the lever 104.- will yield and the spring 106 willtake up the motion imparted by the transverse slide. When the member 27turns in one direction the shoulder 101 will uncover the feeding opening106L in the button feeding means .25, and a button will drop into thesaid intermediate member 27 and will be supported by said shoulder.1When the intermediate mechanism 27 turns in the opposite direction theshoulder 101 will move from underneath the button, and the latter, beingno longer supported will drop down the chute 98. At the same time theshoulder 101 will close the feeding opening 106a.

Mounted on the pivot 1081 of the bracket 100 is a yielding guardconsisting of an arm 109 provided with the finger 110 adjacent to thefeeding` opening 106. This guard is normally held in its uppermostposition by the spring 111, and when a button becomes jammed in thefeeding opening 106L the guard will yield, and then push the button backinto the button feeding device 25 as soon as it is free to do so.

The but-ton feeding means 25 may be of any suitable construction andconsists of a casing 112 having a rotatable dial 113, with pockets 114-,in front of which is a hopper 117. The rotatable dial is driven by theworm 115 and worm gear 116. This button feeding means may be providedwith means for turning the buttons right side up as shown in Patent No.547,571.

The auxiliary slide 29 which carries the clamp 80 for the work holderextends longitudinally of the main reciprocating carriage 28 and ismounted in the guides 118. Normally the clamp 8O is held closed againstthe work holder by means of the expansion spring 119 seated on the stem120 and bean ing against the abutment 121 of the carriage and theshoulder 122 of the auxiliary clamp slide 20. Means are provided foropening said clamp, in this instance constructed as follows: 123 is acam, lever pivoted at 1241 to the adjustable bracket 125 of thereciprocating carriage 28. This cam lever' has a cam slot 126, one sideof which is resilient on account of the spring tongue 127, the said slotengaging with a roll 128 on the auxiliary slide 20. 129 is a camprovided with a slot 180 sliding on the stud 181 of the framework. Oneend of this cam is connected to a rocking lever 132 pivoted on theframework at 188 and provided with a slot 1841 engaging the stud 135 ofthe reciprocating can riage 28. As lthe reciprocating carriage 28travels in one direction the cam lever 123 will ride up on the cam L29,which latter is then, owing to its connections, moving in a directionopposite to that of the rcciproeatf ing carriage. The cam slot 126 actson the roll 128 to move the auxiliary slide 29 independently in thereciprocating carriage 28 sul'liciently to open the clamp 80. As the camlever 123 passes the end of the sliding cam 12S), the member 186 on thereciprocating carriage 28 engages with the stop 187 on the arm 158pivoted on the framework at 185). This arm has a spring 1-10 whichengages the stud 141 on the cam lever 123 and moves it down quicklybehind the cam 129, thus allowing the spring 119 to close the clamp 30.(.)n the return stroke of the reciprocating carriage 28 the beveledsurface 1-1-2 of the cam lever 123 moves the hinged leaf lil-8 of thecam 129 to one side so that the clamp remains closed and permitting thecam lever 128 to pass the cam 129.

11i-il, is an ejector which passes through the aperture 145 in thecarriage 28 and expels or loosons the finished button.

The drilling' tools 31 and niching tools 32 are of any suitableconstruction, but the particular arrangement preferred is as follows:The converging drilling tools 81 are mounted in the bearings 146 on theslide 147 which is adjustable by means of bolts 111:8. Ou the slide11117 is a. bracket 111:9 supporting the steady rest 150 adj usi-,ablein the guides 151 of the bracket 1119 by means of the bolt '152. 158indicates turnbnckles whereby the tools 31 are adjusted. Motion isimparted to the tools by means ot' the belts 154-. passing over thepulleys 155 and 156. The pulleys 156 are on the power shaft 157 whichcarries the fast and loose pulleys 158 adjacent t'o which is a beltshifter 150.

The niching tools 82 are carried in the bearings 160, 161 and 162mounted on the supporting member 84, and converge in the same manner asthe drilling tools.

The bearing 160 consists of a casing 168 having a vertical slot 161.lVithin the easing is a stem 165 which receives the screws 166, passingthrough the slot 116-1-, These screws 166 carry the brackets 167,through which the tools 82 pass.

The bearing 161 comprises a casing 168 having two spindles 160 and 170connected together by means of the pin 1.71 screwed into 16S) andhaving' a head 172 sliding in the slot 173 of spindle 170. The tools 82pass through two brackets 171iwhich are secured respectively to thespindles 16S) and V1.70 by means of the screws 175 passing through theholes 176 in the casing.

The bearing 162 is formed of a casing 177 having two independentspindles 178, each provided with a threaded stem 179 having a tlmmbscrew180. The tools 82 pass through the brackets 181, which latter `areattached to the spindles 178 by means of CFI screws 182. Rotation isimparted to the niching tools 82 by means of the pulleys 183, belt 184:and pulley 185 on the power shaft 157.

rlhe operation of the machine is as follows: Upon motion being imparted,the reciprocating carriage'travels toward the drilling tools 31, therebycausing' the clamp 30 to be opened. The work holder 2G is then rotatedso as to position a button blank in line with the drilling and nichingtools. llhis position is indicated in Fig. 7 by 186. it this time alsothe oscillating intermediate device 27 delivers another button blank tothe work holder. The dial 118 is rotating constantly and is always readyto deliver a blank to the intermediate device 2?. As soon as the workholder 26 has been turned one step, the clamp 8O moves against the workholder 28 and clamps the button. All. during this period the mainreciprocating carriage 28 has been approaching the drilling tools, andthe niching tools have followed it, but owing to the eccentric 39, theniching slide 83 lags behind and the niching tools 82 have receded intime to permit the rotation of the work holder 26. 'lhe drills nowengage the button 8'?, entering the said button from the back anddrilling the holes 188 in the button part-way through. rfhereciprocating carriage 28 now begins its return stroke and moves thebutton out of engagement with the drills. The nichingl tools also movebackward, but, owing to the eccentric 89, at a less rate of speed thanthe carriage 28, and the result is thatl the niching tools engage theface of the button and remove the material in line with and between theholes 188 by cutting the niche or thread groove 189. The niching' toolsoscillate and vibrate continuously by reason of the eccentric 59 so thatthe niche is cnt on a curved line 190 shown in llfig. 22. Theoscillating and vibrating movement of the niching tool is shown in llig.20 where the two dotted positions of the tool are shown nearer thebutton blank than the full line central position. r1`he line 19() inFig. 22 approximately shows the line of movement of the niching` tool.As the carriage 28 reaches the end of its movement, the ejector 144ienters theaperture 145 in the carriage 28, and ejccts the button in linewith said ejector. This button was cted upon by the drilling' andniching tools daring the cycle preceding the one 1 have described andwas moved into position in alincment with the ejector when the workholder was rotated during' the forward movement of the carriage 28.
